Name of the Vulnerable Software and Affected Versions mem0 version 1.0.0

Description The server lacks authentication and authorization controls for memory reset and table re-creation functionality. An unauthenticated attacker can send a request to the 'DELETE /memories' endpoint to trigger a reset operation, which executes a CREATE TABLE SQL statement. This process can result in unexpected table re-creation, schema disruption, potential data loss, and a denial of service for the memory management service.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability. Restrict access to the 'DELETE /memories' endpoint to minimize the risk of exploitation.
